Sigma MC-11 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to Sony E)

Sigma MC-11 Mount Converter (Canon EF to Sony E)
The Sigma MC-11 Mount Converter is a sophisticated bridge that allows you to seamlessly use Sigma Canon EF-mount lenses on Sony E-mount mirrorless camera bodies. Unlike standard “dumb” adapters, the MC-11 features advanced internal electronics that maintain full communication between the lens and camera, ensuring that your Sigma glass performs as if it were natively designed for the Sony system.

Seamless Integration & Performance
Full Electronic Communication: Retains complete support for Autofocus (AF) and Auto-Exposure (AE). It is compatible with Sony’s advanced AF features, including Eye-AF and Phase-Detection, depending on the camera body used.

Correction & Stabilization: Supports in-camera peripheral illumination, chromatic aberration, and distortion correction technologies. It also fully enables in-camera image stabilization (IBIS) for steadier handheld shots.

Data Preservation: Transmits full Exif data to the camera, ensuring your focal length, aperture, and lens information are correctly recorded in your image files for easier post-production.

Precision Engineering
Anti-Reflective Interior: The internal barrel is flocked (lined with light-absorbing material) to eliminate internal reflections and flare, preserving the high contrast and color fidelity of your premium optics.

LED Compatibility Indicator: An integrated LED on the side of the adapter provides an instant visual check of lens compatibility and status when attached to the camera body.

Updateable Firmware: The adapter can be updated via the included data cable to ensure compatibility with future lenses and camera firmware updates.
